DC's don't continue a chain but they will start one. You can kill a DC or EP and then kill an EM to get a chain 1. But if you killed a DC and then another DC you'll only get the base exp. ~Tora
It's not that the DC added to the chain, it was just killed for EXP between the two mobs that contributed to the chain.
You kill an EM and get chain 1, kill a DC and get exp, then kill another EM fast enough to get chain 2 and yes it will keep your chain.
